Objective To probe into the feasibility and applicability of the foodborne food risk monitoring and sentinel hospital foodborne disease surveillance on the Salmonella serotype identification by liquid phase suspension array. Methods The serotyping of Salmonella isolates was performed by traditional glass agglutination test. Meanwhile, the liquid phase suspension array was operated to analyze the antigen O, H and AT for classification identification. Results From 2012 to 2019, a total of 215 strains of Salmonella were collected divided into 38 serotypes, 96% of them could be analyzed by SSA kit. The results of xMAP were in accordance with the traditional agglutination. 8 of the 11 strains which cannot be checked out by glass agglutination seemed to be easy detected by liquid phase suspension array. Conclusion The liquid phase suspension array has advantages of high throughput, high sensitivity and high specificity. It is able to detect the Salmonella serotype rapidly during a short time. Compared with the traditional serum agglutination method, the liquid phase suspension array has obvious advantages in detection time. It can be useful and important in the break out of foodborne disease caused by Salmonella spp.
